The {{Nihongo|'''Tokyo Metro Yurakucho Line'''|東京メトロ有楽町線|Tōkyō Metoro Yūrakuchō-sen}} is a [[rapid transit|subway]] line in Japan owned and operated by [[Tokyo Metro]]. The line connects [[Wakōshi Station]] in [[Wakō, Saitama]] and [[Shin-Kiba Station]] in [[Kōtō, Tokyo]]. On maps, diagrams and signboards, the line is shown using the color "gold", and its stations are given numbers using the letter "Y".

The line was named after the [[Yūrakuchō]] business district in [[Chiyoda, Tokyo]]. The proper name as given in an annual report of the [[Ministry of Land, Infrastructure and Transport (Japan)|Ministry of Land, Infrastructure and Transport]] is {{Nihongo|Line No. 8 Yūrakuchō Line|8号線有楽町線|Hachi-gō-sen Yūrakuchō-sen}}.<ref>株式会社電気車研究会・鉄道図書刊行会。{{Nihongo|鉄道要覧|Tetsudō Yōran}}。 (Issued every September)</ref> According to the Tokyo urban transportation plan, however, it is more complicated. The line number assigned to the section south from Kotake-Mukaihara to Shin-Kiba is Line 8, but that north of Kotake-Mukaihara to Wakōshi is Line 13, which indicates the section is a portion of [[Tokyo Metro Fukutoshin Line|Fukutoshin Line]] which shares the same number.{{Citation needed|date=February 2010}}

==Services==
The Yurakucho Line runs generally northwest to southeast between [[Wakōshi Station]] in [[Saitama Prefecture]] and [[Shin-Kiba Station]] in [[Kōtō Ward]]. Although it was originally planned as a bypass for the established [[Tokyo Metro Marunouchi Line|Marunouchi Line]] through central Tokyo, it was also built to serve the developing wards of [[Itabashi]], [[Nerima]], [[Toshima]], and Koto. The section between Wakōshi and Kotake-mukaihara shares tracks with its sister line, the [[Tokyo Metro Fukutoshin Line]].

The Yurakucho Line has [[through train|inter-running counterparts]] on its northern side, both of which are "major" Japanese [[private railway]] companies in [[Greater Tokyo]]. One is the [[Tobu Railway]] at Wakōshi, north to {{STN|Shinrin-kōen|x|Saitama}}. The other is the [[Seibu Railway]] at {{STN|Kotake-Mukaihara|x}} with its bypass line [[Seibu Yūrakuchō Line]] connecting to its main [[Seibu Ikebukuro Line|Ikebukuro Line]], through trains north to {{STN|Kotesashi|x}} or {{STN|Hannō|x}}.

According to the [[Tokyo Metropolitan Bureau of Transportation]], as of June 2009 the Yurakucho Line is the fifth most crowded subway line in Tokyo, at its peak running at 173% capacity between [[Higashi-Ikebukuro Station|Higashi-Ikebukuro]] and [[Gokokuji Station|Gokokuji]] stations.<ref>''[[Metropolis (free magazine)|Metropolis]]'', [http://archive.metropolis.co.jp/tokyo/794/page2.asp "Commute", June 12, 2009, p. 07.] Capacity is defined as all passengers having a seat or a strap or door railing to hold on to.</ref>

{{nihongo|Semi-express|準急}} services ran on the Yurakucho Line between 14 June 2008 and 6 March 2010, operating twice hourly between Wakōshi and Shin-Kiba. Between Wakōshi and Ikebukuro, semi-express trains stopped only at Kotake-Mukaihara; between Ikebukuro and Shin-Kiba, trains stopped at all stations. The semi-express trains ran between rush hours during weekdays and more frequently on weekends and holidays. These services were abolished and replaced with local services on 6 March 2010.<ref>{{Cite web |date=2010-02-03 |title= |script-title=ja:3月6日（土）有楽町線・副都心線のダイヤ改正 |trans-title=Yurakucho and Fukutoshin Line timetable changes from 6 March (Saturday) |url=https://www.tokyometro.jp/news/2010/2010-06.html |access-date=2010-03-06 |website=Tokyo Metro |language=ja |publication-place=Japan}}</ref>

==History==
[[File:Tokyo Metro Yūrakuchō Line plan.jpg|thumb|Tokyo Metro Yurakucho Line diagram]]
[[File:Sakuradamon st01s3200.jpg|thumb|[[Sakuradamon Station]] exit]]
The Yurakucho line was first proposed in 1962 along with the [[Tokyo Metro Chiyoda Line|Chiyoda Line]]. It was originally envisioned to run between [[Nakamurabashi Station]] and [[Kinshicho Station]]. In 1968, it was later revised to run between [[Chikatetsu-narimasu Station]] in the northwest and [[Shintomichō Station]] in the southeast; the extensions to Wakoshi and Shin-kiba were not confirmed at the time.

Line 8 was planned to serve areas that were not served by the Tokyo subway network such as Nerima and Koto Wards, while providing an adequate bypass for the overcrowding [[Tokyo Metro Marunouchi Line|Marunouchi Line]] from Ikebukuro to Ginza-itchōme.<ref>{{Cite web |date=3 June 2024 |title= 埼玉県和光市と東京のウォーターフロントを結ぶ有楽町線の計画から全線開通まで|trans-title=From the planning of the Yurakucho Line connecting Wako City, Saitama Prefecture and the waterfront of Tokyo to the opening of the entire line |url=https://metroarchive.jp/content/ebook_yurakucho.html/|website=Metro Archive}}</ref> This initial section began construction in 1970 and opened for revenue service on 30 October 1974 as the Yūrakuchō Line. In the late 1970s, the extensions towards Wakoshi and Shin-kiba were authorized.
